Stearylamine Polyoxyethylene Ether AC-1810 (CAS: 26635-75-6) is a non-ionic surfactant with weakly cationic characteristics, appearing as a light yellow liquid to paste. Its molecular structure contains both a long-chain octadecyl hydrophobic group and a polyoxyethylene hydrophilic chain segment, endowing it with outstanding emulsifying ability, wetting and dispersing performance, as well as excellent stability against acids, alkalis, and hard water, enabling high efficiency in complex systems.
With its multiple functional properties, AC-1810 is extensively used in six industry sectors: as a high-efficiency leveling agent and antistatic agent in textile printing and dyeing; as an emulsifier to enhance the spreading and penetration of pesticide formulations; as an emulsifying and solubilizing component in daily chemical products; as a corrosion inhibitor in metalworking fluids; as a demulsifier component in the petroleum industry to promote oil-water separation; and as an internal antistatic agent in the plastics industry to reduce surface resistance.

Textile Printing and Dyeing Industry: As a high-efficiency leveling agent, AC-1810 significantly improves the uniform distribution of dyes on fibers, enhancing dye migration and levelness. Meanwhile, its weakly cationic property imparts excellent antistatic performance to synthetic fibers, reducing static buildup during processing and use. It is recommended to be used in combination with other auxiliaries in the dye bath, with the specific dosage optimized based on the dyeing process and fiber type.
Pesticide Formulations: Used as an emulsifier in emulsifiable concentrates, emulsion concentrates, and microemulsions, it effectively disperses and stabilizes pesticide active ingredients, enhancing the wetting, spreading, and penetration of the spray liquid, thereby improving control efficacy. Its excellent acid-base stability makes it suitable for various pesticide active ingredient systems.
Daily Chemical Industry: In creams, lotions, shampoos, and other cleansing and care products, AC-1810 provides both emulsifying and solubilizing functions, helping oil-soluble components to disperse evenly and improving the transparency and long-term stability of the formulation.
Metalworking Fluids: As a corrosion inhibitor, it forms a protective film on metal surfaces, inhibiting rust, extending the service life of cutting fluids, rust preventives, and other products, and protecting tools and workpiece surfaces.
Petroleum Industry: Used as a demulsifier component, it rapidly breaks crude oil emulsions, promoting oil-water separation and improving the efficiency of crude oil dehydration and desalting.
Plastics Industry: Applied via internal addition or surface coating as an antistatic agent, it effectively reduces the surface resistance of plastic products, preventing dust attraction and electrostatic discharge risks.
